Class RegistryConfiguration

java.lang.Object

com.google.crypto.tink.Configuration

com.google.crypto.tink.internal.InternalConfiguration

com.google.crypto.tink.internal.RegistryConfiguration

public final class RegistryConfiguration
extends InternalConfiguration

Represents the configuration as currently specified by the registry. That is, this configuration is just a thin layer forwarding calls to the global Registry.

Because the global Registry changes when user code adds to it, using this class is not recommended.

Method Summary

Modifier and Type	Method and Description
static InternalConfiguration	createFromPrimitiveRegistry(PrimitiveRegistry registry) Do not call.
static RegistryConfiguration	get()
Class<?>	getInputPrimitiveClass(Class<?> wrapperClassObject) Given the target class, reveals primitive set of what type should be provided to the InternalConfiguration.wrap method in order to get a wrapped object of the target class.
<P> P	getLegacyPrimitive(KeyData keyData, Class<P> primitiveClass) Creates a primitive from a key in the old (proto) format.
<P> P	getPrimitive(Key key, Class<P> primitiveClass) Given a key and a desired primitive class, creates the required primitive.
<B,P> P	wrap(PrimitiveSet<B> primitiveSet, Class<P> clazz) Wraps the primitives in the primitive set into the provided class.

get

public static RegistryConfiguration get()

getLegacyPrimitive

public <P> P getLegacyPrimitive(KeyData keyData,
                                Class<P> primitiveClass)
                         throws GeneralSecurityException

Description copied from class: InternalConfiguration

Creates a primitive from a key in the old (proto) format.

Specified by:

getLegacyPrimitive in class InternalConfiguration

Throws:

GeneralSecurityException

getPrimitive

public <P> P getPrimitive(Key key,
                          Class<P> primitiveClass)
                   throws GeneralSecurityException

Description copied from class: InternalConfiguration

Given a key and a desired primitive class, creates the required primitive.

Specified by:

getPrimitive in class InternalConfiguration

Throws:

GeneralSecurityException

wrap

public <B,P> P wrap(PrimitiveSet<B> primitiveSet,
                    Class<P> clazz)
             throws GeneralSecurityException

Description copied from class: InternalConfiguration

Wraps the primitives in the primitive set into the provided class.

Specified by:

wrap in class InternalConfiguration

Throws:

GeneralSecurityException - if the wrapper for the provided pair (input class, wrapped class) is not registered

getInputPrimitiveClass

@Nullable
public Class<?> getInputPrimitiveClass(Class<?> wrapperClassObject)

Description copied from class: InternalConfiguration

Given the target class, reveals primitive set of what type should be provided to the InternalConfiguration.wrap method in order to get a wrapped object of the target class.

Specified by:

getInputPrimitiveClass in class InternalConfiguration

createFromPrimitiveRegistry

public static InternalConfiguration createFromPrimitiveRegistry(PrimitiveRegistry registry)

Do not call.

We shadow the function createFromPrimitiveRegistry here so that one cannot invoke the static function in the superclass by writing RegistryConfiguration.createFromPrimitiveRegistry.
